Why can’t I send anyone any Sats?

I go to all y’all profiles and tap the Lightning logo to “Pay Invoice”

I then select my wallet (Muun) but it then returns with:

“Is it a LNURL withdraw?

This is a valid LNURL, but not for this

operation. Please, double-check its source

Keep in mind you can only use LNURL to

withdraw funds.”
